An address based data packet network capable of high speeds (10/100/1,000Mbs) originally developed for the computer industry that is seeing adoption in the marine industry. Ethernet networks are designed as a star topology. Systems of three or more nodes require a hub, router or switch to facilitate all point to point connections. An NMEA standard for the transfer of NMEA 2000 messages using an Ethernet protocol is being developed that will be called OneNet.
There are numerous cabling systems for Ethernet but the ones applicable to Raymarine installations include:
RayNet to RayNet Cables
The new RayNet (F) to RayNet (F) network cable can be used to daisy-chain 2 adjacent RayNet devices together. It is also useful for joining two adjacent HS-5 Network Switches together on larger systems where multiple switches are necessary. This network cable is 15-inches (400mm) long.
This cable joins our existing line of RayNet interconnect cables available in 400mm, 2, 5, 10 or 20 metre lengths.
